While I'm accepting Davr's answer for that reason, it was Chris Marshall and John Meagher who turned me on to javap, so thanks to all three of you. Since javap -c output is also identical for the two class files, I am going to conclude that Davr's right and the vendor sent me a placebo. What other steps could I take to determine the difference between the two files? class files are different sizes and I see differences in the output of od -x, so they're definitely not identical. JAD and JReversePro both decompile and disassemble (respectively) the two versions to the same output. class files side by side, the one extracted from the currently running version and the updated one from the vendor. In short, it is a freeware standalone windows application which converts bytecode(.class) files to java source code.

Also, it is not available for Mac or Linux OS. The main drawback of Cavaj is that it lacks syntax highlighting.

In the past, applying patches from this vendor have caused new and completely unrelated problems to arise, so I want to understand the change being made even before applying it to a test instance. It is simple to use and decompiles nearly any java class file. That should pick up the file differences, although it will likely pick up 'insignificant' differences, for example if variables have been named differently in the two versions. class file that is supposed to resolve an issue we're having with the software. You could try using a diff tool (such as SourceGears free DiffMerge tool) on the decompiled sources. I've received a patch from the vendor in the form of a new.
